The unsafeguarded CIRUS reactor, set to run until 2010, could then generate enough plutonium for another 10 warheads.
India subsequently defended its 1974 nuclear warhead test, which relied on CIRUS plutonium, as a peaceful nuclear explosion* The Canada-India agreement, termed the Colombo Plan Reactor Project, is available at http://www.
First, India was able to harvest its plutonium because the CIRUS
reactor was not governed by any nuclear safeguards and second, there had been enormous technical transfers and assistance to India's nuclear program in the 1950s and 1960s.
India took her first steps into the world of nuclear technology in 1956 when she purchased the CIRUS research reactor from Canada.
According to Leonard Spector, India has never advocated her right to use plutonium from the CIRUS reactor in the manufacture of nuclear explosives.
